Attending were SEB members Mike Simanyi, Brian Conners, Mike Brausen, Bob Davis, Zack Barnes, Eric Hyman, and Marshall Grice; Doug Gill and Howard Duncan of the National Staff; Bob Dowie and Earl Hurlbut of the BOD. These minutes are presented in topical order rather than the order discussed. Unless noted otherwise the effective date for all rule, class, and listing change proposals herein is 1/1/2018. Comments regarding items published herein should be directed via the website www. soloeventsboard.com Recommended Items for 2018 The following subjects will be referred to the Board of Directors for approval. Address all comments, both for and against, to the Solo Events Board. It is the BoD s policy to withhold voting on a rules change until there has been input from the membership on the presented rules. Member input is suggested and encouraged. Please send your comments via the form at General #18648 Fuel cell ground clearance rule change The following package of rule change proposals is intended to more consistently address issues pertaining to fuel cell installation: - Change 16.1.D.2.d to read as follows: d. The fuel tank may be modified or replaced. If the fuel tank is modified or replaced, the following restrictions apply: 1. The fuel tank/cell may be located within the same area as the OE tank. 2. If the fuel tank/cell does not fit within the same area as the OE tank, the requirements of must be met. - Move from 16.1.D.2.d to new B.26 and amend as follows: 26. For those categories which permit fuel cells and/or fuel tank modifications or replacements, the following requirements apply if the fuel tank/cell does not fit within the same area as the OE tank: a) No part of the fuel tank or fuel cell shall be closer than 6.0 (15.2 cm) to the ground unless enclosed within the bodywork and mounted above the floor pan. A metal bulkhead is required that provides total separation between the driver compartment and the compartment containing the fuel tank and/or filler/ neck. This includes fuel tanks that are flush mounted with driver compartment panels or otherwise exposed to the driver compartment. Fuel filler doors in the driver compartment must be positively fastened (non-metallic fasteners are not allowed). For the purposes of these rules, a fuel tank consisting of a structure containing a fuel bladder is considered to be the entire fuel cell including the containing structure. The containing structure of a fuel cell does not qualify as a bulkhead. A separate metal bulkhead must isolate the fuel cell from the passenger compartment. b) Internal body panels may be modified to accommodate the installation of the fuel tank as long as such modifications serve no other purpose. In the event installation includes encroachment into the driver s compartment, a metal bulkhead shall prevent exposure of the driver to the fuel tank. c) Fuel tank breathers shall not vent into the driver/passenger compartment.

2 - Change 17.2.Q.1 as follows: Member Advisories 1. The fuel tank may be modified or replaced. If the fuel tank is modified or replaced, the following restrictions apply: a. The fuel tank/cell may be located within the same area as the OE tank. b. If the fuel tank/cell does not fit within the same area as the OE tank, the requirements of must be met. #21740 Application for Advisory Committee The SEB has approved the addition of Jordan Towns to the SAC. #22076 AC Personnel The SEB thanks Mark Pilson for his service on the SAC. Change Proposals and ST #21094 Octane Rating The following revised version of a previously published rule change proposal is provided by the SEB for member review and comment. Add to the end of the first sentence of 3.6.A as follows: and Touring category vehicles will use fuel which is Federally approved for use on public highways, and which does not exceed an octane rating of 93 (per (R+M)/2), with an allowed variance of up to Fuel may not exceed 15% ethanol. Touring #14648 ECU Clarification The STAC would like to clarify the context of the following group of rule proposals: ECU Clarification, Octane Rating (see above), and Making ST Hot Again (see below). The proposal regarding the changes to allow open ECUs (open boost via changes in the ECU) and plug-and-play engine control modules is intended to address the inability to enforce the current rule, while continuing to allow common tuning modifications. The proposal to create STH is also influenced by the potential changes to ECUs/boost. By placing the majority of turbocharged cars in the ST classes together, the impact of boost/engine performance changes would be relatively contained and we would maintain stability in STS and STX. Cars that are moved may be re-classed if warranted. #21408 Making ST Hot again In order to address the issues associated with anticipated changes to open boost, while improving the competitive diversity, the STAC proposes making the following changes to ST, with the exception of removing the displacement catch-alls. - Updated proposed changes for 2018 in conjunction with Touring H: Move from STX to STU Mini Cooper S Turbo ( ) - Proposed changes to wheel and tire allowances for 2018/ STH. AWD would see a 1 inch increase in wheel width and still be limited to a 245 wifth tire. SCCA Fastrack News June 2017 Page 3

3 14.3 TIRES Tires must meet the eligibility requirements of the category with the following additional restrictions: Tires shall have a section width up to and including the following (mm): STS (AWD), STR (AWD) STH (AWD), STX(AWD) STR (2WD), STU (2WD, mid-engine, rear-engine) STH (2WD),STX (2WD), STU (AWD) STU (2WD, front-engine) STP (all) WHEELS Any wheels are allowed with widths up to the following (OE wheels exceeding these maximums are not permitted) (in.): STS, & STR (AWD) STH (ALL) STX & STR (2WD) STU, STP (all) #21610 Comment on #14648 Please see the response in item #14648 #21796 Please evaluate and reclass Porsche 986S and 987S The STAC has provided the following proposed class changes for Porsche MR platforms. Move from STU to STR: Porsche Boxster (986 and 987.1) ( ) Boxster S (986) ( ) Cayman (987.1) ( ) # ECU Clarification Please see the response in item #14648 Prepared #21866 Allowance of Aluminum Head for Ford Kent Crossflow 1600cc The PAC feels that allowing the Formula Ford Kent Pierce aluminum cylinder head to be used in the TVR 1600 will not cause an imbalance in D-Prepared. The aluminum head is 19 lbs. lighter, but makes no additional power. This allowance will make sourcing replacement parts easier. The committee is requesting member feedback regarding a proposed listing addition in Appendix A, which would be as follows: TVR 1800 Vixen S2 (1599 cc) Other Items Reviewed Alternate cylinder head: Aluminum Pierce casting # Audi TT RS Specification Information Thank you for your input. The SAC will class this car when it becomes available. SCCA Fastrack News June 2017 Page 4

The SAC will class the 2018 ZL1 1LE when it becomes available. Touring #21196, 21199, 21205, 21216, 21219, 21221, 21224, 21225, 21229, 21238, 21242, 21260, 21269, 21323, 21346, 21380, 21426, 21471, 21496, 21508, 21528, 21622, 21652, 21676, Feedback regarding ECU Allowances (various) Please see the response in item #14648 Prepared #21396 Move limited edition Mazdaspeed mx5 out of BSP Thank you for your input. Please see the response to letter in the May Fastrack. Not Recommended #21726 New Ford Mustang Package, Class Needed Thank you for your input. Since these RTR packages are dealer installed accessories they are excluded from category. Please see the definition of Standard Part in Section 12. #21751 Move of Mazda RX8 to D- Thank you for your input. The SAC will continue to monitor the competitive balance in CS and DS. # GT3 is obsolete in SS. Thank you for your input. The SAC will continue to monitor the competitive balance between SS and AS. #21781 Move 2008 Mugen Si back to HS Thank you for your input. This car was never actually classed in HS due to its rarity, and was mistakenly omitted from the 2016 rulebook and subsequently corrected. The SAC believes the Mugen Si is appropriately classed in GS. #21787 Allowable Wheel Diameter Changes Thank you for your input. The SAC feels the current wheel allowance of +/- 1 provides competitors with adequate tire fitment alternatives. #21918 Reclass the Honda S2000 from BS to CS Thank you for your input. The SAC will continue to closely monitor the competitive balance between BS and CS. Touring #21843 Add MR2 Turbo and MR2 Supercharged to new STH Class The MR2 S/C is currently classed in STR. The STAC believes the MR2 Turbo is not appropriate for any ST class at this time. Thank you for your input. #21856 Consider adding Turbo to NA cars in STH Thank you for your letter but this idea exceeds the level of preparation seen in Touring. SCCA Fastrack News June 2017 Page 5
